Route Description: Usually done from Theresa Avenue, Rontree Estate, following the Pipe Track/Contour path all the way to Corridor ravine. As one starts up Corridor ravine path, a bushed up track leads off towards Corridor Buttress, around the base of the steep rock band with some negotiation through trees, and into Oudekraal ravine. The ravine is climbed initially on the left of the stream, then crosses it to go up a tributary slope on the right next to the  Oudekraal Ridge which leads out onto the vlakte in front of Grootkop.
